Pregunta

Utilizamos una función para implementar archivos que son comunes a nuestros webparts a la biblioteca de estilo en SharePoint Server 2010 y recientemente nos encontramos con el problema donde los archivos no se estaban actualizando cuando implementamos una versión actualizada de la función. (Nota: Utilizo el término "Versión" Aquí, no estamos versionando nuestras webparts). Después de buscar, encontré que este problema (es decir, los módulos implementarán la versión inicial de un archivo pero no la actualizarán) se ha documentado en una serie de blogs. La conclusión de todos fue que para actualizar los archivos, debe hacerlo programáticamente utilizando un destacado. Encontré un par de soluciones diferentes:

para las soluciones de Farm WebPart:

Probé ambas soluciones sino que terminé yendo con la solución de Johan con algunos ajustes menores para nuestro escenario.

Me encontré con una NullReferenceException cuando corrí el código de Johan, pero esto fue porque no tenemos un atributo de camino en nuestro elemento del módulo. Reemplacé la llamada para recuperar el atributo Ruta con una llamada para recuperar el atributo URL. Luego me encontré con el siguiente error: 

The URL ‘[url]‘ is invalid. It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web

He encontrado varios blogs diferentes que describen soluciones para este error, pero ninguno lo ha resuelto para mí:

* Los enlaces se eliminan, ya que soy más que un Newbie humilde que no puede publicar más de 2 enlaces;) *

¿Alguien tiene alguna otra sugerencia aparte de los registros?

NOTA: Estamos usando una solución agrícola, no una solución de arena.

¿Fue útil?

Solución

After doing a lot of reading and after debugging the feature receiver, I discovered two things:

  1. One of our files (which was introduced after the original version was deployed but before the current version) didn't exist in the Style Library on the SharePoint site. i.e. it had never been deployed. I checked a couple of our test servers and the file wasn't there either so this confirmed it wasn't isolated to my dev machine. This "missing" file was the file throwing the Invalid URL error when SPWeb.Files.Add was called. I confirmed that the file did exist in the hive and that the Add method could create new files. I had a look at what SPWeb.GetFile() was returning. Interestingly enough, the SPFile object returned when retrieving the "virtual file" had Exists = true... but... the file doesn't exist on the server??? (Interesting post here on SPWeb.GetFile(): http://blog.mastykarz.nl/inconvenient-spwebgetfilestring/). I switched to using GetFileOrFolder() and casting to SPFile but my problem still wasn't resolved.

  2. After looking again at Johan's code, I decided to see if there was something else in the call to Add that could be causing an issue. I re-examined our elements.xml file to see if the entry for the "missing" file was different from the other file entries. This ended up being where my problem was... the entry for the "missing" file didn't have all of the attributes that other entries had. In particular, it was missing the Type and IgnoreIfExists attributes.

    <File Path="Style Library\Assets\Scripts\JQuery\JQueryDollarFix.js" Url="Assets/Scripts/JQuery/JQueryDollarFix.js" />

    I updated the entry to be:

    <File Path="Style Library\Assets\Scripts\JQuery\JQueryDollarFix.js" Url="Assets/Scripts/JQuery/JQueryDollarFix.js" Type="GhostableInLibrary" IgnoreIfAlreadyExists="True"/>

    I re-deployed the wsp to the SharePoint site and activated the feature. The FeatureReceiver code ran successfully and the files were updated and checked into the Style Library.

    Feature Receiver Properties Extension (I put this in its own class in the same project as the feature):
